I am investigating the photometric properties and kinematic irregularities of Active Galactic Nuclei host galaxies locally and at a redshift of 1. I also research tomographic adaptive optics technologies that will enable diffraction-limited imaging and spectroscopy over a wide-field (1-2') at visible wavelengths on 5-10 meter class telescopes with laser guide stars. Other research avenues include composite deformable mirrors and the use of cosmic telescopes to magnify light from distant galaxies.
